It’s exciting to see Shyamalan on such confident footing once more, all these years later.
I am not sure I entirely understand the deer. In "The Ring Two," Rachel and her young son Aidan visit a farmer's market. Aidan wanders off and observes some deer that emerge from a nearby forest and stare at him. He stares back.
Later, as mother and son are driving down a little-traveled road, a deer appears in front of their car. "Keep moving," Aidan says urgently, but his mother hesitates, and soon the car is under attack by a dozen stags, their antlers crashing through the windows. She speeds away and hits another stag, doing considerable damage to her front end.
This is in a movie that also involves a mysterious video that brings death to whoever watches it, unless they pass it on to someone else within a week. The video is connected to the death of a young girl named Samara who had a cruel childhood. Samara's ghost is trying to possess Aidan's body. Because she died at the bottom of a well, much water is produced wherever her ghost manifests itself. Usually the water is on the floor, but sometimes it flows up to the ceiling.
Rachel visits the old farm where girl was mistreated and died. In the basement, she finds antlers. A whole lot of antlers. So maybe the deer sense Samara's ghost's presence in Aidan and are attacking the car in revenge? But Samara was presumably not the deer hunter, being far too occupied as a cruelly mistreated little girl at the time. So is it that the deer are psychic, but not very bright?
